This driver was released in 2000.
When this happened on my 1999 ml 320, it was the crank shaft positioning sensor. After replacement-problem solved.
1: disconnect the drive shaft from the rear axle. 2: disconnect the front shaft from the transmission (tedious and you need the correct size tool). 3: disassemble the front shaft from the main shaft by pulling them apart from the center or in front of the support and drop the main shaft. 5: remove bolts holding the support and drop and remove the front shaft shaft with the support still connected. 6: remove and replace the support with a wheel puller. 7: replace support with new part. 8: reassemble in reverse.
